Genius Loci

(Latin). The tutelary deity of a place.

“In the midst of this wreck of ancient books and utensils, with a
gravity equal to [that of] Marius among the ruins of Carthage, sat a
large black cat, which, to a superstitious eye, might have presented
the genius loci, the tutelar demon of the apartment.” —SirW.Scott: The Antiquary, chap. iii.
